PNEUMATIC STACKER.

SPECIFICATION forming part of Letters Patent No. 566,841, dated September 1, 1896.

Application filed April 18, 1896. Serial No. 588,145. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANK B. OHARROIN, of La Porte, La Porte county, Indiana, have invented certain new and useful Improvements in Pneumatic Stackers, of which the following is a specification.

This invention pertains to improvements in the construction of pneumatic stackers and will be readily understood from the following description,taken in connection with the accompanying drawings, in which Figure 1 is a side elevation of an automatic stacker exemplifying myimprovements; Fig. 2, a plan of the same, the elevating-rig being I 5 omitted; Fig. 3, a vertical transverse section in the plane of line a of Fig. 1; Fig. 4, avertical transverse section in the plane of line b of Fig. 1; Fig. 5, a horizontal section, enlarged, of a portion of the telescopic tubewall in the plane of line cof Fig. 1; Fig. 6, a similar view at the collar 21 of the tube, and Fig. 7 a plan of one of the cable-spools.

In the drawings, 1 indicates the usual turntable of the pneumatic stacker, to be mounted 2 5 and provided as is customary; 2, a segmental tube-section carried, as usual, by the turntable; 3, the usual main body of the stackert-ube; 4, the usual curved heel of the body engaging the pipe 2, whereby the body 3 is 0 permitted to have its outer end raised or lowered by the movement of part 4 on part 2, or to swing sidewise by the movement of the turn-table; 5, the elevating-rig, of not unusual construction, carried by the turn-table and serving as means for elevating and securing the tube at desired angles to the horizontal; 6, a tube-section telescoped upon the outer end of tube-body 3; '7, 8, and 9, successive telescopic tube-sections, the drawings 40 showing the telescopic sections fully extended; 10, a guide-bar disposed above and parallel with the general tube; 11, a clip, which may also be a band, rigidly secured to the outer section 9 and to the outer end of guidebar 1O; 12, a roller disposed over the heel of the guide-bar and mounted in a clip rigidly secured to body-section 3; 13, a second roller engaging under the guide-bar and forward of roller 12 and similarly supported by a clip on the body-section, the result being that guide-bar 10 forms a boom supported at its heel by the rollers 12 and 13 and in turn supporting the outer end of the telescopic tube, the rollers permitting longitudinal movement of the guide-bar with reference to body-section 3 as the telescopic tube is extended or retracted; 14, a windingshaft mounted in bearings carried by the heel of body-section 3; 15, a crank on this shaft; 16, a spool fast on the winding-shaft; 1'7, a cable winding upon spool 16 and having its forward end attached to a rearward portion of guide-bar 10, whereby, when the windin gshaft is turned, cable 17 is wound up and the guide-bar drawn rearwardly and the telescope-tube retracted; 18, an adjustable eyebolt carried by the heel of the guide-bar; 19,

a sheave fast with roller 13; 20, a cable going from eyebolt 18 to and over sheave 19 and back to spool 16, on which it winds in a direction opposite to that of the winding of cable 17, the result being that by turning the winding-shaft in proper direction cable 20 draws forward on the guide-bar and extends the telescopic tube, cable 17 paying out to the same extent, the telescopic tube being thus extended or retracted by turning the winding-shaft in one or the other direction; 21, a collar mounted for free rotation on the forward end of outer tubesection 9; 22, an adjustable hood at the mouth of the tube i and trunnioned to collar 21; 23, a second spool on the winding-shaft; 24, a cable winding on spool 23 and extending forward to an arm on the hood 22, so that the turning of the spool may adjust the angular position of the hood upon its trunnions, spool 23 being loose upon the windin g-shaft; 25, a collar fast upon the winding-shaft and having in its face a circular series of holes; 26, a clutch-pin projecting from spool 32 into engagement with a selected one of the holes in collar 27, a spring urging spool 32 toward collar 25,

so as to keep the clutch-pin in engagement, the arrangement being obviously such that the spool may be moved endwise out of clutching engagement and then turned and reclutched in new relationship to the windingshaft; 28, the trnnnions connecting hood 22 with collar 21; 29, springs tending to move the hood in one angular direction upon its trunnions as opposed to the strain of cable 24;

30', a pair of sheaves carried on angular axes at theforward endof guide-bar over collar aspool upon the windingsha'ft; 3 2 and 33,

- spools mounted upon thewinding-shaft for ner. surfaces 'of the rear ends of the telescopic the cables 31, these spools being loose upon the winding-shaft andiclutched theretmas is also spool 23; 34, beadsswaged upon the insections and upouthe outersurfaceof their thin sheet metal, and the internal and externa-l beadingslrform guides and stops for the telescopic action and also stifien the extremi- 1 and lowered in the usual way by the operaforward ends, and 35 bails rigidly secured to thetelescopicsections and en gaging loosely overtheguidei-bar 10,-wherebythe telescopic sections are suspended from the guidebar. The tube parts are formed of comparatively tiesiof the tube-sections. I The tube is raised tionof elevating-rig Sand is turnedby the isextendedr or retracted bythe operation of usual operationof the turn-tahlel The tube Spool 16on cables 17 and 2a Hood-22 is ad 7 justed upon itstrunnions 2S bywin ding more q rotationofcollar 21 uponthetube, by the ment is therefore not disturbed as the tube or less of cable 2lupon spool 23,1which,-by unclutching it, maybe turned and fixed in 1 any desired relationship to the winding-shaft.

To adjust collar 21 and thus swivel the hood so as to cause the tube to discharge into corners, as when working in barns, spool 32 or 33 is unclutched and unwound to give the desired slack of cable, after which the other one of the two spools is wound up to produce the adjustment of hood. Trunnions 28 engage open bearings in collar 21, thus permitting the hood to be removed by unhooking its springs and Withdrawing its trunnions from their bearings, thus permitting the tube to swing in a specially shortradius. Sheave 19 and roller 13 are of the same diameter, the result being that the outward movement of the guide-bar, in extending the tube, is produced partly by friction of roller 13 on the bar and partly by the strain of cable 20 upon eyebolt 18, which eyebolt permits of the cable being kept taut.

I claim as my invention 1. In a pneumatic stacker, the combination, substantially as set forth, of a turn-table, a segmental pipe-section thereon, a sheet-metal tube-body having a segmental heel engaging said pipe section, successive sheet metal tapering telescopic tube-sections at the outer end of said tube-body, beads swaged out- 7 wardly atthe forward-ends of said telescopic tube-sections, and beads swaged inwardly at the -innerendsof said telescopic sections.
